Sernin. 712,499. ou mam Y v To @ZZ whom-L't-nmy concern: v Be it know-ntliat I, LUDWIG ,BEKEL- MANN, a citizen of the United States, residing at Davenport, in the county of Scoltand State i 5 of Iowa, have invented certainnew and'use-H ful Improvements i-nl Metallic lWinfl-oiirShutters, of which the followingis a specification.v This invention relates to certain new and uscfulimproveinentsin metallic(windowlsliut- Io ter's,fand particularly to that class of `metallic shutters which are providedwith afseries of "vertically adjustable slats .adapted to be` raised one uponthe other to open the sh utter andto descend of their ownl weight when .it-l

is desiredfto closeth'e shutter.

15 l l Theinv'ention has for its moreiinnrediateobf ject thefimprovem ent upon the particular construction of shutters described and claimed in Patent No.301g429, granted to n`1e July l', 188,4.

In the`construetion described and' shown in said patent' each slat slides in an independent` -'groo".e;con"structed in the window-frame? practical use this construction has been fo und I to 4be objectionable owingto the trouble-and framean'd 't'o the additional fact that theslats willfbind'in the groovesandlrender the shut- I ter use1ess'.` 1 '4 l q The essential object of'this ipvention is to j shutter simple and' economical in str u'ctnr and sureand easy of operation, and, further,'

to provide a superior and ecientmeans' for?.

Flocking the shutte'r ina closed positio'nfV vention may 'pertain 'l the 'same 'eonsistsin-the .novel construction and in 4the proper/arrange;

' ment, co n1bination',and adaptationof parts,

. all'as more fully described, shown in the ac- 4 A fined'intheappended claims.

. Referring to. the drawings, .Figure lll'shows.

metallic frame which shall fit within the openl .i Ying left in the wall by In v expense in constructing,thesey grooves in. the.

overcome these objections' 1and-to p'rovide a through suitable holes To these endsand to suchl others as-'the'in companying drawing's, and l'specifically de-.f

Fig. 6 is a detail of the builder or within the windowfcasing..- l The exposedvportionoff this frame may be as ornamental as desired.

The vertical sid-e pieces at of tl1e me tall`c 55 -frame are provided with notches b, adapted Lto 'fori'n a seat for tlie'slats when in alowered position. k (lest shownin Fig.` 3.)' The inctallic 'plates orjslats c are allowed to descend from the top. i All of the slats c arcorn the s am'c 6o 'size' and shape. .n I

On the inside of each ofthe innenyertical framefpieces d is. p'rovideda rib e`,' which may the 'pressed or struck lin the 'side' 'pieces-d. 'These ribs al'e'notitruly"Z perp'endiculz'tr,butls-vv are made on 'a slantextendingfrom of the upperp'ortion of the flrarne'tok the'front of the-lower portion thereof, (about'a's shown innig. s.) w

'c at each end are .sec'uredthe,horizontal rear-V wardly-extend'ing arns or guides. f, which are.l cutout or provided'witha groo'vewhichcorresponds with the rib e and fits around the same', as shown lin Fig..4. Thus the slat-sMc-'i are guided in their upwardrand downward movementvby thearms fand the .rib e;

On the inside of. the lower corners of"l the bottom plate c are secured-.two rings' or. eyes y g; in eacliof which is fastenedthe oneend 8o of a lineorjcabl'e gif Thse lines 'thenpass Y, up and Vover smal-l pul-leywheels h; secured tothe underfsideof 'the upper' part of the frame. Thelines". then pass 1"horizontally,

and easing and are secured to the spools'fi i, which are .rigidly s ecixred'Y upon the horizon- Atal shaft j. Thisshavft is supported by suitable" brackets 7c 7c, securedi'to the windowcasi-ng. Near one endv of the shaft j is rigidly 9ov secured asproeketwheel Z with any desired number o f teethl or cogs. Nearthe lower portion of the window-casing and on the in-- side is'securedanother-siuiilarsprocket-wheel W1/,placed at. right angles `to the one above, 95 and between this sprocket and the windowcasing is placed a s rnall ratchet n with a pawl secured to the window-.casing adapted to engage `the same. The shaft or spindle to which thesprocliet and ratchet are secured projects 1 oo :outward beyond the sprocket'a'sutable disjtance, and this protrndingend is made square,

Near the upperzedgeofthe nslats or plates :7o-

in' the ,window frame v85 so that a key or crank may be applied thereto for operating the shaft. The two sprocketwheels l and m are connected by an endless chain p, which owing to the relative position of the two sprocket-wheels necessarily has a quarter-twist.

Assuming that the shutter is closedthat is, each slat rests in one of the notches b, the bottom Slat resting on the lower part of the metallic frame, as shown in Fig. S-A-it will now be seen that by placing the key or crank o upon the shaft jourpaled in the window-easing and turning the same to the right the horizontal shaft j will rotate. ,The lines or cables will be wound upon the spools t' 1T and being fastened to the lower slat c will raise such slat, the bottom slat will come in contact with the slat next above it, raising that one, and so on to the top one, if it is desired to entirely open the shutter, the slats or plates being guided by the armsj, which in turn are guided by the iibs c.

The parts may be held stationary at any point?, as the pawl engaging the ratchet will prevent their descent until the pawl is thrownout of engagement with the teeth of the ratchet-wheel, and when this is done it will readily be seen that the parts will descend of their own weight, (but may be controlled by the crank or key 0,) the upper slat dropping in the first notch, and so on to the bottom.

I provide a novel means of locking my iinproved shutter, which is as follows. To the bottoni slat and at its center I journal the arm 1/having its outer end preferably of a square shape for a purpose to be presently set forth. Rigidly secured to this arm u and adjacent to the slat is a flat piece of Inet-al g, provided with a hole in each end. Into these holes are fastened the ends of the bolts fr r, which are curved at their inner ends about as shown in Fig. 5. These bolts a-re held in a horizontal position by the guides or eyes s :i s s. A hole tis provided in the sides of the frame (l. Journaled in the window-casing and in a bracket y, secured to the sill of the window, is a shaft :13. This shaft has an enlarged inner end Il' and the outer end squared, so that the key rr can be readily attached to said outer end for-rotating the shaft. A recess .'r ifcut in the enlarged portion w of the shaft .1', corresponding to and adapted to receive the square ond of the arm u when the slats are l lowered. the slats descend the square end of the arm *ztwill readily enter the recess m', and by turning the key u to the rightfthe shaft and arm will rotate and the ends of the bolts r r will enter the holes t and securely lock the slats. To unlock the slats,it is only necessary to turn the key 'o in the opposite direction. It will also be apparent that. by constructingr the shaft .r with theenlarged end w, havingarecess 1v', that when the slats are unlocked the arm u rests in lthe reeessrz;i in such aposition that it is capable of heilig withdrawn from said recess and ascending freely with the bottoni slat.

Having thus described my invention, what i claim as new, and desire io secure by Letters Patent, is

l. 1n ashutter, a frame, notches in ille 0pposite sides of the frame, a series of slats adapted to rest in said notches, rearwardlyextendng arms at the upper corners of thc slats, recesses in the outer side of each arin, inclined guide-ribs constructed in the sides of the frame and adapted to enter said recesses, whereby the slats are drawn inward when ascendingso as to fall one within the other substantially as described.

2. In a shutter, a frame, notches in the opposite sides of the fraine,a series of verticallyadjustable slats adapted to rest in said not-ches, a locking device consisting of an arlin journaled in the lower slat at its center, a plate rigidly secured upon the arm adjacent to said slat, bolts pivotalty7 secured to the ends of the plate and adapted to enter recesses in the frame, a shaft journaled in the windoweasing and in a bracket secured to the sill of the window, an enlarged portion on the inner end of the shaft., a recess in said enlarged portionadapted to receive the outer end of the arm journaled to the center of the lower slat, when the slats are lowered, whereby saidarin may be rotated by turning akcy secured to the outer end of the aforesaid shaft, substantially as described.

Inv testimony whereof l affix my signature in presence of two witnesses.
